AlchemillaHQ/Sylve v0.2.0 on GitHub

Sylve v0.2.0 improves reliability and day-to-day usability with a new telemetry backend, better clustering behavior, VM/jail workflow upgrades, and broad UI polish.

Highlights

VM + Jail templating support and improved lifecycle flows.
New telemetry database and migrations for CPU, RAM, swap, network interface statistics, and audit data.
Cluster reliability improvements, including version mismatch guard on join.
Console attachment support and VM logging improvements.
Networking/storage updates (dynamic DHCP lease deletion, improved ZFS and downloader/uploader flows).

Migration Note

If you previously used a custom RAFT port (clustering), migrate by re-bootstrapping RAFT:

Ensure 8180 (RAFT Port), 8183 (Cluster SSH), and 8184 (Intra-cluster HTTPS API) are open between nodes.
Stop Sylve on all nodes.
On the follower nodes, reset the cluster state (Reset Cluster button in the Datacenter -> Cluster page), then after all followers are gone, reset the leader node as well.
Create a new cluster

8183 and 8184 were already fixed; 8180 is now standardized and no longer configurable, this was done to prevent misconfiguration and improve user experience.
